The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is an invasive insect pest of soybean [Glycine max (L.)Merr. (Fabaceae)] in North America, and it has led to extensive insecticide use in northern soybean-growing regions there. Host plant resistance is one potential alternative strategy for managing soybean aphid. Several Rag genes that show antibiosis and antixenosis to soybe...

In 1992, a detection survey for Heterodera glycines (soybean cyst nematode) was conducted in 16 counties in Michigan. The nematode was detected in 12 counties, with absolute frequencies ranging from 6 to 100%. A total of 149 samples was collected, and 53% were infested with H. glycines. Eighty-four growers participated in the survey, and 38 had samples collected from more than one field. Of the...

Soybean mosaic virus (SMV) and peanut mottle virus (PMV) are two potyviruses that cause yield losses and reduce seed quality in infested soybean (Glycine max (L.) Merr.) fields throughout the world. Rsv1 and Rpv1 are genes that provide soybean with resistance to SMV and PMV, respectively. Isolating and characterizing Rsv1 and Rpv1 are instrumental in providing insight into the molecular mechani...

Soybean [Glycine max L. (Merr.)] is an important legume crop, with annual global production of 367.8 million tons. The seeds contain about 20% oil dry weight, which mainly used for extraction, and the improvement soybean quality a critical subject world-wide. We isolated several fatty acid accumulation mutants identified corresponding genes. Next, we attempted to improve using these mutant succ...

The current study was carried out to investigate the effect of dietary inclusion of soybean hull on performance, carcass characteristics and blood parameters of broiler chickens from the age of 1 to 42 days. A total of 240 day-old broiler chickens (Ross 308) which were randomly assigned to 4 dietary treatments with 5 replicates of 12 birds in each replicate. Experimental treatments were control...

Two experiments were conducted to evaluate the effects of adding combinations of wheat middlings (midds), distillers dried grains with solubles (DDGS), and choice white grease (CWG) to growing-finishing pig diets on growth, carcass traits, and carcass fat quality. In Exp. 1, 288 pigs (average initial BW = 46.6 kg) were used in an 84-d experiment with pens of pigs randomly allotted to 1 of 4 tre...

Molecular makers linked to quantitative trait loci (QTL) can assist soybean [Glycine max (L.) Merr.] breeders to combine traits of low heritability, such as yield, with disease resistance. The objective of this study was to identify markers linked to yield QTL in two recombinant inbred line (RIL) populations ['Essex' x 'Forrest' (ExF; n = 100) and 'Flyer' x 'Hartwig' (FxH; n = 94)] that also se...

Here, we compare the molecular mechanism of soybean heterosis through the differential expression of basic cloning. Specifically, we cloned 22 differentially expressed cDNA fragments from hybrid combinations of Jilin 38 x EXP (which had obvious yield advantages) and their parents. In addition, we compared the homology of these fragments and predicted their functions. Cloning differentially expr...

The efficacies of Heterodera glycines-resistant 'Fayene' soybean and aldicarb for managing H. glycines were compared to the experimental nematicides DS-47187 10F, DS-47357 10F, DS-48145 10F, DS-48165 10F, DS-46995 10F and 5G, and DS-38697 5G during 1981-83. Yield of Fayette was greater than yield of the H. glycines-susceptible cultivar treated with nematicide in 1981 and 1983. Yield of aldicarb...
